[转载]Spring Web MVC Framework

Required Configuration

You need to map requests that you want the DispatcherServlet to handle, by using a URL mapping in the web.xml file. The following is an example to show declaration and mapping

for HelloWebDispatcherServlet example:

<web-app id="WebApp_ID" version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
    <display-name>Spring MVC Application</display-name>
   <servlet>
<servlet-name>HelloWeb</servlet-name>
<servlet-class>
         org.springframework.web.servlet.DispatcherServlet
      </servlet-class>
      <load-on-startup>1</load-on-startup>
</servlet>
   <servlet-mapping>
<servlet-name>HelloWeb</servlet-name>
<url-pattern>*.jsp</url-pattern>
   </servlet-mapping>
</web-app>

The web.xml file will be kept WebContent/WEB-INF directory of your web application. OK, upon initialization of HelloWeb DispatcherServlet, the framework will try to load the application context from a file named [servlet-name]-servlet.xml located in the application's WebContent/WEB- INF directory. In this case our file will be HelloWeb-servlet.xml.
